Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 3-(3,5-dichlorophenyl)-3-oxopropanoate.
Ethyl 3-(3,5-dichlorophenyl)-3-oxopropanoate (CAS 172168-01-3) is a high-purity analytical reference standard with the molecular formula C11H10Cl2O3 and a molecular weight of 261.10 g/mol.
Based on its molecular formula C11H10Cl2O3, Ethyl 3-(3,5-dichlorophenyl)-3-oxopropanoate contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 261.10 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
